Where several conductors are to be connected, the difference between the wires/cables
used must not exceed one DIN Standard size level.
Bei Mehrleiteranschluss darf maximal ein DIN-Normgrößen-Sprung zwischen den
verwendeten Leitern liegen.
En cas de raccordement de plusieurs conducteurs, il faut 1 écartement normalisé max.
entre les conducteurs.
In caso di collegamento a più conduttori, è ammesso al massimo un salto di grandezze
DIN standard fra i conduttori utilizzati.
En caso de conexión de múltiples conductores puede haber como máximo un salto de

Sizing Guide
TheDFEis designedforgeneralpurpose applicationsandwherea traditionalStar/
Delta is currently used, or would be considered to be appropriate. Generally the
motorwillstartoffload,andthetimetoacceleratetofullspeedwillbeintheregion
ofafewseconds.
Thestandard DFE range is suitable for the majority of cases, and conforms to Trip
Class5, which means it is capable of withstanding 3 times Full Load Current for 5
secondstarts.Howeverthereare instanceswhereadifferentstartisrequiredand to
satisfy this situation the DFE has four further ratings, Class 10B, Class 10, Class
20andClass30.Theseratings correspond to IECthermal/electronicoverloadtrip
classes,andtheDFEmust be used with anovercurrentprotectiondevicethat has
aratingcorrespondingtotheTripClassselected.
Whenusingthefollowingtablestoselectthe mostappropriatemodelofDFEplease
note
· The DFE is not suitable for very high inertia loads such as centrifuges
or loaded crushers with starts > 30 seconds (Fairford has other
ranges of Soft Starter for these applications)
· Do not use the Class 5 rating when there is possibility of the motor
starting with a significant load.
· 2-pole motors may take longer to start, use a minimum of
Trip Class 10B.
